While we are at the feasibility of "zombie virus" spread...
The "Walking Dead" series actually introduced a workaround, which is basically that the virus is airborne and everyone is already infected, the virus just waits until you are actually dead to make you, well, be less dead and more sorta move around getting all hungry for human flash. What bugs me about this "solution" is that the "bite" infections make no sense anymore, meaning that they should be no less dangerous than a bullet wound or any semi-serious injury yet everyone still treats the zombie bites as a death (ok, "undeath") sentence.
They did at one point offer some bullshit explanation, like the zombie bite has a large concentration of bacteria which greatly reduces your chance of surviving the bite which technically makes it turn you into a zombie faster, but this a) actually muddles things a bit too much kinda hurting the issue more than it helps it and b) still doesn't explain why a bite is an automatic death sentence since the "bacteria cocktail" will have different ingredients for each zombie that manages to bite you. If you are the very first victim of a new zombie who up until the zombification had a great dental hygiene than a small nibble should be approximately as dangerous as a tiny papercut. But try explaining *that* to the crazy ***** adamant to put a knife into your brain ASAP.
TWD didn't invent that, it was the basic staple of the original Romero films (prior to which 'zombie' referred to the Haitan voodoo legend, not the present concept of zombies - even in the 1st of the Romero series, Night of the Dead, the shooting script says 'ghoul' instead of 'zombie').
In the old Romero films, nobody knows what's causing the dead to rise - the 'virus' idea is one hypothesis that some characters consider, but it's just one of many ideas that different characters come up with, ranging from the scientific (e.g. the virus idea) to the claim that it's a divine curse, and ultimately nobody actually knows (and nobody ever finds out) in any of the films.
If I recall correctly, early in Dawn of the Dead (Romero's original 1970 version, not Snyder's remake), after the military raid at the start, it's mentioned that they've already cleared all the zombies from the city several times over. Romero's central idea is that society is already on the verge of collapse under the weight of humanities worst attributes (he was a rather angry disillusioned Vietnam veteran writing towards the end of the 60s) - the zombies aren't supposed to be a threat to any well-functioning society. They're just the slight push that topples the already rotten social structure (also why in each of his films, the characters would survive easily if they could actually trust and work together (Night of the Dead, Day), suppress their tribalism and greed instead of going to war over resources when there's plenty for both sides (Dawn), or are pitted against each other in a conflict only tangentially related to the zombies (Land).
TWD (both the comic and the tv series) is a tribute to the Romero films - they're basically just taking the Romero setting, but putting it in modern time instead of having the dead start rising in the late 1960s (the time of the first film in Romero's series). The first edition of the comic has a foreword by the writer where he says that's why none of the characters will use the word 'zombie' - as it's a tribute to the Romero-verse, and in the Romero films nobody calls them zombies for the excellent reason that prior to the Romero films, the word 'zombie' had a different meaning.
